AUTOMOBILE-SANDER.

Specification of Letters Patent.

Patented July 20, 1920.

Application filed March,10, 1920. Serial No. 364,658.

To all whom it may concern:

Be it hereby known that we, ADoLrH TEUSCHER and 0171 0 Tnosonnn,citizens of the United States, and residents of Hillsdale, county ofMultnomah, and State of Oregon, have invented an Automobile- Sander, ofwhich the following is a spec1- fication.

Our invention relates more particularly to self-propelled vehicles suchas are used without rails, but is also applicable to trailers adapted tobe drawn by such vehicles.

The object of our invention is to provide an exceedingly simple,eflicient and inexpensive means for preventing slippage and skidding ofautomobile wheels.

e accomplish these results in the man-. ner described in thespecification following and illustrated in the accompanying drawing, inwhich V Figure 1 is a perspective diagrammatic view of the deviceshowing its application to a truck. Fig. 2 is an enlarged elevation of asand distributing valve mechanism. Fig. 3 is a sectional plane of Fig.2. Fig. 1 is a detailed elevation of the lower end of the valveoperating lever. Fig. 5 is an enlarged side elevation of the operatingpedal.

Similar numbers of reference refer to the same or similar partsthroughout the several views.

In this drawing We have illustrated the application of our device to atruck whose frame 7 and wheels are shown in dotted lines, and whosefront portion is entirely cut away for clearness. We have constructed adouble sand hopper 8 which branches out laterally in two directions,each portion of which terminates in a throat 9 which is secured to theinside of a hopper funnel 10 by means of the rivets 11. The lowerportion 12 of the hopper funnel 10 is cylindrical in form and contains abutterfly valve 13 which is mounted on a shaft 141 which journals in thewalls of the cylindrical portion 12.

' An operating lever 15 is secured to the shaft 14 and has tapped intoits outer end a screw-eye 16 which is held in correct adjustment by thelock nut 17 Distributing tubes 18 telescope over the outer portion ofthe member 12 and are secured to same by means of the slot 19 in thetube 18 which hooks over the pin 20 in the outside of the member 12. Thelower end of the distributing tubes 18 is positioned to dischar e sandtrack of the wheels 21. b m the The operating cables 22 are attached tothe screw-eye 16. The springs 23 hold the butterfly valves 13 in theclosed position agamst the tension of the cables 22. These cables uniteand are carried forward to the lower end of the brake pedal 24 andthence up through the brake pedal foot pad to an auxiliary toe pedal 25which is hinged by centrally located ears to the upper end of the footpad by means of the eye bolts 27. The cable 22 passes over the requirednumber of guide pulleys 28 to cause any forward action of the toe pedal25 to produce a pull on the cables 22, thereby opening the butterflyvalve 13 at the same time and the same amount.

It will be seen that the sand 31 placed in the hoppers 8 can bedistributed in the track of both wheels at precisely the same time byregulating the position of the screw-eye 16.

S nce it is a well known fact that vehicles equipped with tires withoutground-gripping qualities are a constant source of danger to the publicand property, and as it is known that the conditions most favorable forskidding is the time when the pavement has received its first moistureafter a dry period, it will be seen that the average truck wheel willusually be found without its ground gripping appliances when mostneeded. Furthermore in attempting to negotiate a hill having a smoothpavement it is often found extremely difficult for trucks to,

gain the incline without undue slippage and resulting-strains on theworking parts of the automobile. Furthermore in attempting to stop a carequipped with our device, it will be found that we have provided anexcellent meditun for enabling the truck wheels to maintain their gripon the ground.

While we have thus illustrated and described our invention it is not ourdesire to limit ourselves to this precise form or .method ofapplication, but intend that it shall cover all forms and modificationsthat fall fairly within the appended claims.

lVhat we claim as new and desire to protect by Letters Patent of theUnited States, is:

1. In a device for preventing the skidding of automobile wheels, thecombination of a sand containing receptacle, delivery tubes adapted tocarry the sand from said receptacle t0 the Wheel track, butterfly valvesWithin said delivery tubes, spring return cables adapted to operate saidbutterfly valves, and a toe operated pedal mounted on the brake cables.7 2. A mechanlsm for actuating a sand conpedal adapted to actuate saidtrolling valve of the character described,

consisting of a toe pedal centrally pivoted 0n the upper end of thebrake pedal and 15 the point of attachment to said controlling 20 ADOLPHTEUsoHER. OTTO TEUSCHER.
